General Motors have announced that a defect affecting vehicles safety exists in certain 2018 GMC Terrain vehicles, and they will be asking owners to return to their dealerships to have the problem repaired.

According to the defect report, the sensing diagnostic module (SDM) used to deploy the airbags during a crash, may not power down correctly when the vehicle is powered off. If this happens, the SDM could become inoperative, and when the vehicle is started the airbags may not deploy in the event of a crash. Drivers will be alerted of a problem through an illuminated airbag warning lamp, a “service restraint system” message in the main display and an audible warning chime will sound.

GM will notify owners, and dealers will reprogram the SDM with updated software. Owners may contact GMC customer service at 1-800-462-8782. GM’s number for this recall is 18179 and the NHTSA campaign number is 18V-340.
